{PAEBE QEEICE f WM LAIQR- Application filed October 4925. Serial no; 5 87.1;

This invention relatesto improvements in "ventilating apparatus forebuilding struc- I tures, and hasffor its prime object to provide a ventilator which may be readily mounted -in the walls of a buildingso as to providea suitable circulation Ufa-11 at all times;

I A further object of the invention is the pr 'visie pf renewi g epara e adapted to be mounted in elevatedposition so that the air in the upper portion of a room may freely circulate.

part of this specification and in which like numerals are employedto designate corresponding parts throughout the same:

Figure 1 is a fragmentary side elevation of a building showing my improved ventie lating structure mounted thereon.

Figure 2 is an enlarged transverse sectional view through a section of a building wall and ventilator constructed in accordance with my invention and taken substantially upon the line 2 -2 of Figure 1.

, of illustration is shown the preferred em .mains practicallyimmovable.

Figure 8 is a perspective-view in separated position, of my improved ventilator.

In the drawing, wherein for the purpose bodiment of my invention, the numeral 5 generally indicatesthe side wallsof a conventional type of building equipped with a common type of window 6. This building is a simulation of a dwelling and, as is well known, the window 6 is situated in a posi-v tion intermediate the floor and'ceiling of a room therein. While it is customary V to 7 build the window adjacent the ceiling of the room, in many cases the upperend'of the window is a substantial distance below the ceiling so that theupp'erflstrata of air re.- 7 My invention contemplates the use of ventilating structures to be mounted in the building walls'above the window, asapparent from Figure l of the drawing. The provision of *this structure will necessarily cause the air in the upper portion of a room to circulate,

so that the heated; foul air may escape from the room and fresh air enter. f

Beferring now more vparticularly to the structure!embodyingmy invention, the numeral! designates' in its'entirety a 10X like body or casing ofgenerally rectangularformatron composed of a top '8, bottom 9, and

end members 10'. This body as shown "in Figures 2'and8 of the drawing, is preferably constructed ofwood or similar material,

the width thereofbeing arranged toconform to the/Width of the building wall. 'The casing 7 is to be mounted preferably ina longitudinal position in a suitable opening formed in the building wall, the opening be;

ing formed of exact size so that the casing maybe snugly positioned therein.

From the foregoing description and drawing, it is apparent that the sides of the casingare open this being arranged so as'to accommodate detachable side members 12.

,These members are constructed of rectangular formation somewhat larger thanthe contour of the casing so as to over-hang the easing structure. Each of the side members is formed with a rectangular frame emb0dying longitudinal side beams 13. beveled or rounded at their outer portions provided at the center and ends with'grooves. EX tending between the longitudinal beams '13 and connecting therewith are transverse beams 14 of somewhat shorterconstruction, the extremities of these transverse beams being provided with tongues engageable' with r the grooves formed in the side beams. While I haveshown and described a tongue and groove connection between these members, V

the structure is not restricted to this particular form of connection, and any desirable connecting means may be employed. Extending between the longitudinal beams 13 "and connected to the centers thereof by a tongue and groove connection is a central 1 brace bar 15. This bar supports the interior extremities of a plurality of longitudinal bars 16 arranged in spaced intervals and extending between the central bar 15 and the transverse end beams 14, the ends of the longitudinal bars 16 being secured to; the

vertical beams in any suitable manner. 1 is evident, that the side'members 12 Wlll be provided with a plurality of longitudinal rectangular formed openings through which the .airjm'ay readily pass from the exter or to theinterior of a building \Each ventir lator embodies two of. these detachable side members, the exterior member being secured by nailing or similar manner While the interior side member may be securely positioned by screws or the like. The enlarged construction of the apertured side members Haring thus described my invention, I claim:

A, ventilator structure of the character described. comprisinga rectangular casing body open at opposite sides and designed for insertion in a building Wall, a, gratlng designed to be secured over each open side of. said casing and comprising a frame of.

greater orer-all length and iridth than the casing and of substantially the same interior width and length as the same, said grating frames abutting against the Wall faces to secure the structure 111 position 1n the wall,

longitudinally extending and transverse bars n each of said grating frames,and means for securing said grating frames to the hex structure.

In testimony whereof I aflix my signature.
